A variant of the Tromp-Taylor ruleset

[avo]

The variant is essentially the Tromp-Taylor ruleset. It’s a ruleset of Go, not of a Go variant. 
It only differs from the Tromp-Taylor ruleset in that there will be two more legal positions. Can you find them?

I wonder whether you would prefer the variant to the original?

Here is the ruleset:

1: Go is played by two players called black and white on a 19x19 grid of points, each of which may be colored black, white or empty. All points are colored empty at the beginning of the game. The player controlling more points at the end of the game wins.
1.1: The player called C controls point P if either P is colored C or P reaches only C.
1.11: Point P colored C’, not colored C, reaches C, if there is a path of orthogonally adjacent points colored C’ from P to a point colored C. 
2: The players begin the game by alternating turns starting with the player called black; and end the game with two consecutive passes of a turn.
2.1: On one's turn, one makes a move that doesn't repeat an earlier grid coloring.
2.11: If the turn player and the other player are called C and C’ respectively, a move consists of coloring a point colored empty C; then coloring disputed points colored C’ empty; and then coloring disputed points colored C empty.
2.111: Point P is disputed if both players control P.

“The propositions n.1, n.2, n.3, etc., are comments on proposition No. n; the propositions n.m1, n.m2, etc., are comments on the proposition No. n.m; and so on.”

I have been always considering the existence of the capturing rules not so natural since the goal of Go is to control more points instead of capturing more stones. So I designed the ruleset above.

It was designed using a top-down approach starting with the goal of the game - to control more points in the final position.
A legal position is a position that can be used to determine the game result “unambiguously” as the final position.
Any position during the game could be the final position since the players can choose to end the game at any position by passing two consecutive turns.
Therefore, every position during the game must be a legal position.
A legal position is defined to have no disputed points so that it can be used to determine the game result “unambiguously”.
Thus, the capturing rules are needed to prevent illegal positions.

The variant is practically the same as the original, so yes.

This text seems to allow a player's stones to fill the board without liberties.

Indeed.
